Elastic Load Balancer - ELB

An Elastic Load Balancer (ELB) is a service provided by Amazon Web Services (AWS) that distributes traffic across multiple targets, such as Amazon EC2 instances, in one or more AWS regions. The primary purpose of an Elastic Load Balancer is to evenly distribute the load among individual servers or resources, ensuring balanced utilization and enhancing the availability and reliability of applications.

There are various types of Elastic Load Balancers in AWS:

  1. Application Load Balancer (ALB): This load balancer operates at the application layer (Layer 7 of the OSI model) and can distribute traffic based on HTTP and HTTPS requests. An Application Load Balancer is well-suited for modern applications, microservices, and container-based architectures.

  2. Network Load Balancer (NLB): This load balancer operates at the network layer (Layer 4 of the OSI model) and distributes traffic based on IP addresses and TCP/UDP ports. Network Load Balancers are suitable for applications with high data throughput and require extremely low latency.

  3. Classic Load Balancer: This is the older version of the Elastic Load Balancer, capable of operating at both the application and network layers. However, Classic Load Balancers are gradually being replaced by Application Load Balancers and Network Load Balancers.

Configuring an Elastic Load Balancer typically involves using the AWS Management Console, AWS Command Line Interface (CLI), or AWS SDKs. The advantages of Elastic Load Balancers lie in scalability, improved application availability, and automatic distribution of traffic to healthy instances or resources.

Elastic Load Balancers can also be integrated with other AWS services to support additional features such as Auto Scaling, security groups, and SSL/TLS termination. Overall, the use of Elastic Load Balancers provides an efficient way to make applications highly available and performant.

Virtual Private Server - VPS

A virtual server, also known as a Virtual Private Server (VPS), is a virtual instance of a physical server that utilizes resources such as CPU, RAM, storage space, and networking capabilities. A single physical server can host multiple virtual servers, each running independently and in isolation.

This virtualization technology allows multiple virtual servers to operate on a single piece of hardware, with each server functioning like a standalone machine. Each VPS can have its own operating system and can be individually configured and managed as if it were a dedicated machine.

Virtual servers are often used to efficiently utilize resources, reduce costs, and provide greater flexibility in scaling and managing servers. They are popular among web hosting services, developers, and businesses requiring a flexible and scalable infrastructure.

Function as a Service - FaaS

Function-as-a-Service (FaaS) is a cloud computing model that allows developers to execute individual functions or code snippets without having to worry about the underlying infrastructure. Essentially, FaaS enables developers to upload and run code in the form of functions without dealing with the deployment, scaling, or management of server infrastructure.

The idea behind FaaS is that developers only need to write and upload the code that fulfills a specific function. The FaaS platform then handles the execution of this code when triggered by events or requests. A typical example of FaaS is using serverless computing in the cloud, where developers deploy functions in the cloud that run only when needed.

Popular FaaS platforms include AWS Lambda by Amazon Web Services, Azure Functions by Microsoft Azure, and Google Cloud Functions by Google. They allow developers to upload and execute code in various programming languages, simplifying application development and scalability without worrying about the underlying infrastructure.

Serverless

Serverless refers to a cloud computing approach where developers can build and run applications without having to manage the underlying infrastructure, such as servers or server instances. In the serverless model, the responsibility for provisioning, scaling, and maintaining servers lies with a cloud service provider.

Essentially, serverless doesn’t mean there are no servers; it means developers don't need to concern themselves with managing those servers. The infrastructure is automatically managed and scaled by the provider as needed, allowing developers to focus on writing application code without worrying about the underlying hardware or server configuration.

Serverless applications are often broken down into functions or services known as "Function-as-a-Service" (FaaS). Developers write functions that respond to specific events and are managed and executed by the serverless provider. These functions scale on demand and are billed based on actual usage.

Benefits of serverless include improved scalability, cost savings through usage-based billing, reduced operational complexity, and the ability to focus on developing application logic rather than managing infrastructure. It's commonly used for various types of applications such as web applications, APIs, data processing, and more.
